A whistle emitting a loud sound of frequency 540 Hz is whirled in a horizontal circle of radius 2 m and at a constant angular speed of `15 rad//s`. The speed of sound is `330 m//s`. The ratio of the highest to the lowest frequency heard by a listener standing at rest at a large distance from the center of the circle is
